The current patrimonial configuration of the Museum is the result of numerous acquisitions, which have followed since the inauguration in 1962 up to the more recent ones from the Museo delle Origini (2004) and the Museo Preistorico Etnografico L. Pigorini (2005).
The museum heritage essentially consists of two main collections of materials:
The Gorga Collection, with ceramics from the Etruscan and Italic areas, dating from the Archaic to Late Hellenistic periods, and bronze materials of great representativeness in the Etruscan-Italic and Roman fields.
The Rellini Collection, with materials from the Faliscan, Capenate, and Adriatic coast areas.
In April 2004, of great importance was the transfer from the Museo delle Origini of the entire complex of historical age materials found in the excavations of the so-called Faliscan caves, conducted between the late 1800s and the first thirty years of the 1900s by Angelo Pasqui, Raniero Mengarelli, and Ugo Rellini in the territories of Corchiano Falerii.
Very recent, finally, (October 2005) the acquisition of a group of 63 artifacts (architectural and votive terracottas, ceramics, and metalware), once again taken from the vast Gorga collection, deposited at the Museo Preistorico Etnografico L. Pigorini in Rome, which further enrich the Museum’s exhibition panorama.
